In order to study the effectiveness of Choreito in the removal of ureteral stones, 7.5g/day of Choreito was administered to 52 patients who had been diagnosed as having ureteral stones. For stones of a diameter less than 4mm, 63.2% were passed within two weeks, and 78.9% within four weeks. The rates for stones between 4 and 10mm was 10% in two weeks and 33.3% in four weeks. For the 52 cases overall, the rate of stone excretion was 28.8% within two weeks and 50% within four weeks.
There were no side effects observed in conjunction with Choreito administration.
